REVERSIBLE STORE-DOOR LATCH.

SPECIFICATION forming To all whom, it may concern:

Be it known that I, AUGUST AnENs, a citizen of the United States,residing at New Britain, in the county of Hartford and State ofConnecticut, have invented certain new and of which the following is aspecification.

My invention relates to improvements in that class of latches in which alongitudinallymoving latch-bolt is drawn inward by means of a thumb-bar,said latches being known as invention are to provide a simple and cheaparrangement, in the form of a double angle-lever, for throwing the bolt,and t0 makethe piece against which the thumb-bar presses changeablysecured to said angle-lever, so as to project from either side of thecase, to adapt the latch for use upon either a right-hand or a lefthanddoor. I attain these objects by the simple construction illustrated inthe accompanying drawings, in which- Figure 1 is a frontelevation of mylatch with the cap-plate of the case removed; Fig. 2 is a sectional viewof the right-hand side of said latch, the plane of section beingindicated by the line as w in Fig. 1; and Fig. 3 is afront elevation ofparts of said latch.

A designates a longitudinally-moving latchbolt, beveled at its outerend, and, if desired, provided with the anti-friction lever a. Saidlatch-bolt is forcedinward under the influence of the keeper, uponclosing the door, as in other latches, and it is forced outward by meansof a suitable spring, I).

For the purpose of withdrawing the latchbolt A from the keeper when thedoor is closed, I secure the horseshoe-shaped piece B, having suitableengaging-lugs, c c, to the inner end of the latch-bolt. I pivot to thecase at d a T- shaped or double angle-lever, 0, whose ends rest againstthe sides of the engaging-lugs c c, which face the latch-bolt, as shown,while the pivoted post (I is upon the other side of said lugs and inlongitudinal alignment with the latch-bolt. Upon the front face of thelever C are two stubs or posts, h, which are designed to receive, one ata time, the inner end of the vertically-moving slide D. Said slide ispropart of Letters Patent No. 286,250, dated October 9, 1883.

Application filedAngust 4, 1883. (Modem size to fit and receive eitherof said posts h. The upper and lowerside edges, of the case are slottedor recessed toreceive the body of the slide D, near its opposite end,and guide the same in its vertical movement. The lower end of the slideD has a broad head, 70, for the ordinary thumb-bars to act against inlifting the slide D. In view of the fact that this is amortise-latch,the sidewalls of the case are brought nearer together inthe vicinity of the slide than elsewhere, thereby forming the notches mfor the head is ofthe slide, andpreventing said head I from projectingso far beyond the main portion of the side edges of the case as to interfere withinserting the case endwise into a mortise. Instead of two postsh h, a single postmay be placed on the lever C, intermediately betweenthe present location of said posts, and then make the slide Dcorrespondingly longer.

The lock is set in the position shown in the drawings, with the ordinarythumb-bars di rectly underneath the head is of the slides. By operatingeither thumb-bar in the ordinary manner it is pressed upward against thehead of the slide D and lifts said slide. The slide, being connected bythe posts h to the lever C, necessarily imparts a swinging movement tosaid lever and forces the end of its upper arm against the upper lug ofthe horseshoe-shaped,

piece B,- to force said piece and the latch-bolt A inward into theposition indicated for the respective parts by the broken lines in'Fig.1.

and out of its guiding-recess, and place it upon the lever C, with itshead projecting from the other side edge of the case-that is, the edgeopposite that from which it was last removed.

I am aware that store-door latches have been shown. in prior patents ascontaining a vertically-moving slide at one edge of the case for beingacted upon by the thumb bars, said which engaged a lug at the inner endof the 1atch-bolt;'also, as containing a double angle-lever which actedupon engaging-lugs eonnected to the latch-bolt, the middle of whichlever, for being acted upon by the thumb bars, was arranged in themiddle of an opening near the middle of the latch-case, to make thelatch reversible also, as containing a latclrboltn'ith a changeableengaging-lug and a changeable angle-lever, one arm of which was forbeing acted upon by the thumb-bars, the latch being reversed by changingthe lag and angle-lever to either side; and, also, as containing avertically-moving slide bearing a cam for acting upon the engaging-lugof the latch-bolt, and changeable, so that the end designed to be actedupon by the thnmb-bars may be projected from either side of the ease forreversing. All of said prior art is hereby disclaimed.

I claim as my invention-- The combination of the latch-bolt havingsuitable engaging-lugs at its inner end, the double angle-lever, and thevertically-n1oving slide changeably secured to said angle-lever,substantially as described, and for the purpose specified.

AUGUST ARENS.
